"Resolved. That on the application of Mr J. Vint, the new street off My Lady's Road, adjoining Willowfield Church, be called - Jocelyn Street". (Improvement Committee, 24th June 1891).
"Named from Jocelyn Cottage" and grounds, situated on the leading road to Cregagh. It was a neat cottage, with some 20 acres of a land, gardens, plantations, and a porter's lodge". (Belfast Street Names. John J. Marshall).
The name Jocelyn is a Hebrew girl’s name meaning happy, Joyful. The Belfast And Province Of Ulster Directory 1892 indicates that “a few new houses are in the course of erection”. Jocelyn Avenue is clearly well established at this time according to the same addition of the directory. The Belfast And Province Of Ulster Directory 1863-1864 indicates that “Mrs Campbell” lived at Jocelyn Cottage on the Woodstock Road. It is likely the street is called after the cottage. The name Jocelyn is a Hebrew girl’s name meaning happy, Joyful”.
